The technology isn't anything new, but suddenly there's a deluge of touchscreen devices. Can the upcoming iPhone help U.S. consumers kick their keyboard habit?

The first Garmin navigational device with a touchscreen-only interface, the GPSMAP 5212 lets users select routes, maps and other data with a touch of the finger. The GPS device has a large 12-inch, waterproof display and comes preloaded with U.S. coastal charts. Expect to see the device in stores this summer.
